To aZZ whom t may concern:

' Be it known that l, UTAKIOHI KAWASAKI,

a subject of thevEmperor of Japan, resid-- the closure said closurebeing formed of rubber o'r some other similar material and arranged sothat when pressure is applied thereto withV the fingers of the hand theclosure will open on one side and upon release of pressure will springback into closed position and seal the. bottle..

A further object of the invention is to provide a closure which may beoperated to open and seal a bottle or the likewithout necessitatingtouching the mouth of the bottle with the ingers of the hands, Whereby ahighly sanitary closure is provided.

The invention possessesl other advantages and features, some of which,with the foregoing, will be set forth at length. inthe followingdescription wherein I shall outline in full that form of the inventionwhich I have selected for illustration in the drawings accompanying andforming a part of v the present speclcation. ln said drawings,

' claimsv may be embodied in a plurality of I have shown one form of.the construction of my invention, but it is to be understood that I donot limit myself to such form, since the invention as expressed in theforms.

- Figure 1 is a perspective view of a bottle with my improved closuremounted thereon and showingthe closure held open.

Figure 2 isa vertical sectional view taken through the closure showingthe closure as when sealing the bottle. v v i Figure 3 is afrontelevation -of the closure.

Figure 4 Yis a top showing it applied to a bottle.

lln the present 'embodiment of the inven-vy plan view of the closureAtion the closure is in the form of .a flanged -cap formed of one pieceof rubber or other similar material and consists of a body 1 having adepending flange 2. The closure is Aadapted to fitsnugly over the mouth3 of a bottle or like container 4 as shown in Figure 2 of the drawings.

To facilitate opening the bottle the closure is provided with asegmental opening v5 in one side of the flange 2. The lower edge of theflange and the edge ofthe opening 5 are bordered by integral beads 6 and7 which are thicker than the rest of the clo sure and strengthen theclosurelas a whole. The opening 5 is disposed so that the body or top ofthe closure on one sidel thereof lies on the top only of the mouth 3 fora distance equal to the length of the opening and closely engages withsaid mouth-so asto provide an effective sealing of the bottle.

To open the bottle with the. closure applied thereto as shown in'Figure2, pressure is applied to the top or. body 1 ofthe closure by pressingwith the finger downwardly and inwardly from the upper edge of theopening 5 as shown inV Figurel l. This stretches the opening 5 so thatsaid open ving registers with the open mouth of the bottle as shown inFigure 1 andopens the mouthrsuiiciently to permit th`e contents of thebottle to' be poured therefrom.' As soon as the pressure from thefingers is released the body being of 'rubber will spring back intoposition asshown in Figure 2 and seal thevbottle. lBy having the loweredge of the flange 2v and edge ofthe opening 5 provided with the beads61 and 7, these portions are less elastic than the other portions of theclosure and will snugly embrace the4 that a bottle where contactedtherewith so tight seal is insured. Y

The invention consists inthe provision of an elastic closure forbottles,- jars andA the like receptacles, wherein the closure is con?structed so that by stretching the.- material thereof at a certain pointsaid closure will open sufliciently to permit the contents of the bottletoibe removed therefrom and upon release of the pressure said closureWillquickly spring back into sealing positio l claim y 1.
